A word coined in 1948

Américo Castro was not writing about medieval Spain when he wrote about convivencia. He was writing about modern Spain. His 1948 book España en su historia appeared three years into Francisco Franco's dictatorship, when the regime was building national identity around Catholic purity and the erasure of everything Moorish and Jewish from the Spanish past. Castro pushed back. His argument: Spanish civilizational character was forged through the interaction of three communities (Muslims, Christians, and Jews), not despite it.[1]

1948

The year Américo Castro coined convivencia in España en su historia — more than nine centuries after the period it describes. No medieval Spanish source used the term to describe interfaith relations.
The argument had political force and methodological weaknesses that Spanish historians identified almost immediately.
Castro's primary evidence came from literary sources: chronicles, poetry, philosophical texts. He treated these as transparent windows onto lived social reality. Critics noted that he largely ignored legal documents, tax records, and the extensive body of sources describing persecution, legal discrimination, and sporadic violence. Claudio Sánchez-Albornoz, his main Spanish antagonist, argued that convivencia was Castro's projection of 20th-century liberal values onto a society organized by entirely different premises.
The consensus among professional historians since then has been cautious. Eduardo Manzano Moreno, one of Spain's foremost medieval historians, has stated that convivencia has no support in the historical record as a description of systematic interfaith harmony. Mark Cohen, the Princeton scholar of Jewish-Muslim relations, traced the myth back to 19th-century Jewish historians who invented an Andalusian golden age as a polemical tool against European antisemitism. David Nirenberg, in Communities of Violence (1996), argued that periodic violence was not an aberration from coexistence but a constitutive feature of how medieval communities managed their interactions.

What the Umayyad Caliphate actually was

Strip away the debate about the myth and something real remains. Córdoba under the Umayyad Caliphate (929–1031) was a genuinely extraordinary city. By the late 10th century, it held perhaps 500,000 inhabitants, making it the largest city in western Europe, larger than Paris or London by an order of magnitude. The caliphate's libraries were legendary; the court library under Al-Hakam II reportedly held 400,000 volumes at a time when most European monasteries possessed a few dozen. Physicians at the palace drew on Greek, Persian, and Indian medicine without treating the traditions as incompatible.
The intellectuals who came out of this tradition are not mythological figures:[2]

- Averroes (Ibn Rushd, 1126–1198): the most thorough commentator on Aristotle in medieval history. Thomas Aquinas called him simply the Commentator. - Maimonides (Ibn Maymoun, 1138–1204): born in the Judería twelve years after Averroes, the greatest medieval Jewish philosopher, whose Guide for the Perplexed engaged directly with Aristotelian philosophy. - Ibn Hazm (994–1064): Muslim theologian and jurist who produced one of the most systematic catalogues of world religions ever written.
This intellectual culture was real. The question is what social and political conditions produced it.
The legal framework was the dhimmi system. Non-Muslims (dhimmis, meaning protected peoples) were allowed to practice their religions, maintain community institutions, and live under their own internal law. In exchange, they paid the jizya poll tax, accepted formal subordination to Muslim political authority, and operated under restrictions that varied considerably by ruler and period. A 10th-century Umayyad document from Córdoba explicitly forbids dhimmis from constructing new temples.[3] Jews and Christians were protected. They were not equals.
The distinction matters. An arrangement that produces philosophical collaboration between elite scholars is not the same thing as structural religious tolerance. The intellectual culture of Umayyad Córdoba was real; Castro's reading of what it meant was a different claim entirely.

The ornament and its critics

María Rosa Menocal's The Ornament of the World (2002) did more than any academic monograph to export the convivencia narrative into English-language public discourse. Menocal, a professor at Yale, wrote a passionate book arguing that medieval Andalusia produced "a whole series of golden ages" in which the three Abrahamic faiths generated culture together rather than despite each other. The book was widely praised, widely read, and widely assigned in undergraduate courses.
It was also challenged, sometimes fiercely.
Darío Fernández-Morera's The Myth of the Andalusian Paradise (2016) assembled a counterargument that leaned heavily on primary Arabic sources Menocal had not used, or had read differently. His thesis was stark: the convivencia narrative is a modern political construction with no adequate foundation in the historical record. Medieval Andalusia was not more tolerant than contemporary Christian Europe. Fernández-Morera argued it was in important respects less so, particularly in its treatment of apostasy and in the formal legal disabilities imposed on dhimmis.
The debate between these two positions remains genuinely unresolved, but academic opinion has moved significantly toward the skeptics.[4] The current scholarly reading sits somewhere like this:
Interior of the Mezquita-Catedral of Córdoba, convivencia's most cited monument, showing red-and-white striped double arches of jasper and marble receding into shadow, the Renaissance cathedral nave visible in the background, photorealistic golden-hour light

The Mezquita, completed by Abd al-Rahman I in 786 and expanded by his successors for three centuries, now contains a 16th-century cathedral at its heart: the most visible monument to three eras sharing one space, though sharing is not the same as coexisting on equal terms.

- The Umayyad caliphate produced real conditions for intellectual exchange at the elite level, through court patronage and a political culture that valued expertise regardless of religious origin - This was not a structural condition of tolerance but a political choice by specific rulers within a legal framework that formally subordinated non-Muslims - The intellectual achievements were concentrated among court-connected elites; extension to the general population is not demonstrated by the sources - The narrative of golden-age convivencia is historiographically recent, not a description medieval Iberian communities would have recognized
The honest answer to "did convivencia exist?" is that something happened in Córdoba that allowed manuscripts in three languages to move between scholars of three faiths. That something was more complex and more conditional than either the tourist brochure or the outright debunker admits.

The violence that tolerance forgot

The convivencia thesis, even in its most qualified form, runs into a specific problem: the events of 1066 and 1391.
On 30 December 1066, in the taifa city of Granada, a Muslim mob stormed the royal palace, killed Joseph ibn Naghrela (the Jewish vizier to the Berber king Badis al-Muzaffar), and massacred much of Granada's Jewish community.[5] Estimates of those killed reach 4,000, though the historian Brian Catlos has argued the violence was more targeted than the traditional account suggests, focused on the vizier's circle rather than the general population. The disagreement about scale does not resolve the underlying point: a Jewish minister was killed by a crowd inflamed by resentment of Jewish political power, and the event demonstrates the structural fragility of dhimmi protection. It depended on political favour. When that favour ended, so did the protection.
The 1391 pogroms were worse. On 6 June 1391, a mob in Seville followed the inflammatory sermons of the Archdeacon Ferrán Martínez, attacking the Jewish quarter.[6] Within three months, the violence had spread to Córdoba, Toledo, Valencia, Barcelona, and more than 70 cities across Castile and Aragon. Thousands were killed; tens of thousands were forced to choose between baptism and death. The royal authorities, technically obligated to protect the Jewish communities under their jurisdiction, did nothing.
Córdoba, the city that tourism markets as the capital of convivencia, was among the sites of these pogroms. This is not a minor footnote.
The taifa period (post-1031) matters for the same reason. When the Umayyad caliphate fragmented into competing city-states after 1031, religious conflict increased across Andalusia. If structural tolerance had been the norm, fragmentation would not have produced this result so rapidly. The more plausible interpretation is that caliphal authority had constrained sectarian violence, not cultural acceptance but political power. Remove the power, and the constraint goes with it.

Córdoba markets the myth

The modern tourism narrative of Córdoba as the city of three cultures did not emerge organically from the medieval period. It was constructed, and the construction has a clear starting point.
Post-Civil War Spain needed a new national story. Franco's regime had built itself on Catholic reconquest mythology: Spain purified, unified, freed from Moorish contamination. After the dictatorship ended, Spanish cultural institutions looked for counter-narratives. Al-Andalus, specifically the Umayyad Caliphate of Córdoba, offered one. A medieval Spain that had been cosmopolitan, intellectually rich, multi-faith. The political utility was obvious: a usable past that repudiated Francoism without abandoning Spanish pride.
Córdoba's tourism industry absorbed this story and amplified it. The Mezquita-Catedral, the Synagogue, and the Jewish heritage in Córdoba became a triad of monuments representing Muslim, Jewish, and Christian presence. The phrase tres culturas (three cultures) migrated from academic debate into hotel brochures, walking-tour scripts, and municipal marketing.

    Menocal's Ornament of the World

    The English-language popularization of the convivencia thesis reaches a broad readership.

UNESCO heritage branding reinforced the narrative. The Mezquita received World Heritage status in 1984, with the Historic Centre following in 1994. The framing invariably emphasizes the convergence of civilizations. What UNESCO protects is real architecture; what the framing asserts is a historical interpretation that remains contested.
This is not to say the marketing is straightforwardly dishonest. The Mezquita was built by a Muslim dynasty, modified by Christian rulers, and sits in a city that held a significant Jewish community for centuries. Those facts are not invented. What is constructed is the inference from those facts to a conclusion about harmony and tolerance. The historical record does not straightforwardly support that inference.
The city gains something concrete by sustaining the narrative: visitors. The al-Andalus golden age draws tourists who come for the Mezquita and the patios. It also gains something harder to quantify: a positioning as the opposite of cultural exclusivism, a city that embodied pluralism before the word existed. For a country still processing the Civil War and the expulsions of 1492, that positioning carries meaning beyond the tourist map.

What remains when the myth is stripped

The revisionist critique of convivencia does not leave nothing. It leaves something more honest, and in some ways more interesting.
The intellectual vitality of Umayyad Córdoba was real. Averroes and Maimonides are not inventions. The manuscripts that moved between scholars in Arabic, Hebrew, and Latin are documented. The palace library was a real institution. These are not myths in need of correction; they are facts that the convivencia story borrowed and inflated.

Abd al-Rahman I: The Fugitive Who Founded Córdoba

In 750 CE, a 19-year-old Umayyad prince escaped massacre and fled across North Africa. Six years later he founded Córdoba's Emirate and built the Mezquita.

The coexistence was real, in the limited sense that communities existed side by side. Jews lived in Córdoba, prayed in its synagogues, worked as physicians and court officials. Christians did the same. What is in dispute is what that proximity meant for lived experience: whether it produced tolerance, structured exchange, or simply a hierarchy that occasionally permitted contact between its layers.
The oppression was also real. The dhimmi system was not a precursor to modern pluralism. It was a framework of managed subordination that could, under good rulers in good periods, permit genuine intellectual collaboration, and could, under different conditions, leave communities exposed to violence with no structural protection. The 1391 pogroms did not happen because convivencia had broken down. They happened in cities where convivencia was being actively promoted, which tells you something about what the promotion was actually selling.
Córdoba's most honest version of this history would acknowledge all three layers: the genuine intellectual achievement, the legal subordination that framed it, and the violence that punctuated it. That version is harder to fit on a walking-tour script. It also happens to be the actual history: a genuinely complex medieval society that modern tourism, like modern historiography, keeps simplifying in opposite directions.
Stand in the Mezquita long enough, in the forest of 856 columns of jasper, porphyry, and marble, and you feel something that the scholarly debate cannot fully accommodate: that the building is evidence of a civilization capable of extraordinary things. Whether those things required or produced tolerance in any meaningful sense is a question Córdoba's stones cannot answer. The historians are still working on it.
